Tyrosinemia Type I


What is Tyrosinemia Type I?

Tyrosinemia Type I is a genetic disease that happens when a person’s body does not have the enzyme fumarylacetoacetate hydrolase (FAH). This enzyme helps break down tyrosine, a building block of proteins. When this enzyme is absent, a toxic compound, succinylacetone, is produced. The presence of succinylacetone as well as the build up of tyrosine leads to a variety of health complications that can be lethal if left untreated.
